Affective lexica and other resources for Italian

An affective lexicon is a database of words (or word senses, phrases, or other kinds of lexical items) where each item is classified according to its content in terms of subjectivity, polarity (potisive or negative), capability of evoking specific emotions and so on. Such resources are used to build automatic systems that analyze natural language (for example, from websites or social media), and “read” the sentiment expressed in the text. This activity is called Sentiment Analysis (or Opinion Mining) and it is gaining more and more attention from the scientific communities as well as industry, because it can answer questions like “are customers happy with product X?” or “what type of people approve policy Y?”.

Italian is a somewhat poorly represented language in the panorama of language resources. This is true for affective lexica too, but thanks to a vibrant community, things are rapidly changing. I conducted a quick survey, by asking on the mailing list of the Italian Association for Computational Linguistics about affective lexica for Italian. I received many replies, that I compiled in the list below. Some of them are lexica, some are other kinds of resources and methods, either in the Italian language or somehow linked to the Italian NLP community.

A big thank you to all the contributors. If you know of other resources that would fit the list above, feel free to contact me, I’ll be happy to update the list.
